usb: gadget: f_uac: update maxpacket in function bind

Browse Source 
This patch fixes the bug of RV1126 USB crash when configed as
UVC + UAC + RNDIS + ADB. If we resize txfifo before opening
UAC stream, the maxpacket of epin will be the default value
1024 and txfifo will exceed the maximum limit.

Fixes: e658b2131e ("usb: dwc3: gadget: fix tx fifos resize for disabled eps")
